Coordinate maps

A coordinate map plots geographic data points on a map using latitude and longitude coordinates. Each marker represents a document with a geo_point field, and marker size indicates the aggregated value at that location.

When to use coordinate maps

Use coordinate maps to reveal distribution patterns and spatial correlations over locations, such as customer locations, service coverage areas, incident distributions, or events with geographic coordinates. You can select geographic regions to filter other visualizations on the same dashboard. For multi-layer geographic visualizations, use the Maps application.

Creating a coordinate map

The examples on this page use the Sample flight data dataset. Before you begin, complete the prerequisites.

To create a coordinate map, follow these steps:

1. In the New Visualization dialog, select Coordinate Map, then select your index pattern (for example, opensearch_dashboards_sample_data_flights).
2. Set the time filter to Last 7 days.
3. Under Buckets, select Add > Geo coordinates.
4. Set Aggregation to Geohash and Field to OriginLocation.
5. Select Update.

The map displays markers at flight origin locations, with marker size proportional to the document count at each location, as shown in the following image.

Customizing the map display

1. Select the Options tab.
2. Under Map type, select a marker style: Scaled Circle Markers, Shaded Circle Markers, Shaded Geohash Grid, or Heatmap.
3. Adjust Precision to control the geohash bucket size (higher precision = smaller, more numerous buckets).
4. Select Update.
